Muller N.V., Rotterdam, Netherlands Application April 13, 1938, Serial No.201,772 In Germany May 15, 1937 10 Claims. ,(Cl. 131-30) This inventionrelates to Cigar making machines, and more particularly to a means incombination with a wrapping machine for firmly holding the end of theWrapper rst applied to the filler in a manner so that the rst end of thewrapper will readily adapt itself .to the configuration of the filler.

At the present time in the making of cigars by machines the wrapper iscarried to a position for engagement with the filler by a suctioncarrier, the construction of which is well known, and the wrapper is-then removed from the carrier and the free end started on an end of thefiller. The removal of the wrapper from the carrier is accomplished bymeans of a resilient finger which not only removes the initial orstarting end of the wrapper from the carrier, but also applies this endof fthe 'wrapper onto the end of the filler. Due to the varyingconfiguration of the cigar ends difficulty is experienced at the presenttime in snugly applying the starting end of the wrapper on the filler,`and it is, therefore, :an object of this invention to provide a Wrapperapplying means which can be used with varying types of cigar ends andwhich irrespective of the configuration of the end of the cigar fillerwill snugly and firmly apply the starting end of the wrapper on thefiller.

It is `also an object of this invention to provide a Wrapper applyingmeans which is so constructed that it can be accurately timed in itsoperation with the ll-er mechanism so that the cigar production canproceed at a relatively rapid rate.

With the foregoing and -other objects in View, the invention will bemore fully `described hereinafter, land will be more particularlypointed out in lthe claims appended hereto.

Figure 6 is fa detail view'of the parts operating finger 26 of Figure 3.

Figure 7 is a like view but with the feeding finger pressed down furtherand folding the end of the wrapper thereabout.

understood that additional rollers 40 are used to engage about thefiller W for the purpose of tightly wrapping Ithe Wrapper D thereabout.

The' rollers I are secured #to shafts I awhich are journalled inbearings 2 and 3 carried'by the frame structure 2I. Spur gears 4 areX-ed to the shafts I a adjacent the bearing 3 and mesh with a relativelylarge spur gear 5 secured to a countershaft 6. A smaller spur gear 1 isfixed to :the shaft 5 and meshes With a driving gea-r 8 which is -fixedto a drive shaft 9 connected to a suitable source of power. y

The frame 2l is provided with an outstanding arm 2i), and a lever I5 ispivotally mounted on this arm 20 by means of a pin I9 which engages thelever I5 between the ends thereof. The upper end of the arm I5 isprovided with a recess I6, Figure 6, in which a bar I2 engages, and this-bar I2 is adjustably held in the recess I6 by means of a bolt I'Iextending through an elongated slot I8 in the arm I5. The slot I8 isdisposed substantially parallel with the `axes of the shafts I a so.that the adjustment of the bar I2 may be made longitudinally of theshafts Iaand the rollers I.

A socket generally designated as I0 is mounted on or secured to an armII which is provided with a slot I4 adjacent the lower end thereof, andthe arm II is adjustably secured to Ithe bar I2 by means of a bolt I3.In this manner` the arm II may be `adjusted vertically so as to properlyposition the socket I0 with respect to the end Sp of the ller W. Thesock-et I0 is preferably open on its upper side, as at 29 so that theend E of the wrapper D may enter the socket,

and at one side of the opening 29 an upstandingl The wrapper D ispositioned over the ller rolls by means of a movable carrier 25 theoperating features of which are well known and not believed necessary toillustrate. The carrier 25 is provided in its under surface with adownwardly opening slot 21 in which the finger 26 is adapted to engageso as to be positioned on the upper side of the wrapper D.

The socket IU is rocked toward and away from the filler W by means of adisc 24 which is fixed to the drive shaft 9 and which is provided with acam flange 23. 'Ihe lower end of the lever I5 is provided with a roller22 which engages the cam 23, and a spring 2|a yieldingly holds theroller 22 in contact with the cam 23, one end of the spring 2|a beingsecured to a part of the frame 2| and the other end of the spring 2|abeing secured to the lower end of the lever l5.

The spring finger 26 may be mounted on a suitable part of the frame 2|,engaging in a slot 3a provided between the bearings 3, and this finger26 is normally biased to` an uppermost position as shown in full linesin Fig. 3. With reference to Figure 9, the tucking needle 26 is swungdown against the end of the wrapper E by a rod 4| pivoted on the end ofan arm 42 which has its lower end pivoted in a bracket 43 and whichcarries a crank roller 44. A spring 45 on the bracket 43 engages the arm42 and holds the roller 44 yieldingly against the periphery of a disc 46driven through gears 41 from the shaft 9. The disc 46 has a cam orraised portion 48 on its periphery which engages the roller 44 andswings the arm 42 and the rod 4| toward the needle 26, as shown indotted lines in Figure 9. Spaced stops 49 on the needle engage the eyeof the rod 4| and move the needle back and forth with the rod 4|. Theneedle passes through the top of the frame 3 and the forward stop 49tapers to engage the frame and tilt the needle 26 downwardly, as shownin Figure 9 in dotted lines.

In the use and operation of this device, the carrier 25 is swung to aposition where an end of the wrapper D overlies the socket when thesocket is in operative position, or in the position shown in full linesin Fig. 3. The nger 26 is so positioned that the swinging of the carrier25 to a discharging position will also cause the end of the finger 26 toenter the slot 21 above the wrapper D. The finger 26 is then swungdownwardly and as the nger 26 engages the wrapper D inwardly of theadjacent end thereof the downward swinging of the finger 26 will bendthe free end of the wrapper D as shown in Figs. 6 and 1, the end of thewrapper D sliding down along the surface 3|] of the flange 28. Thefiller W at this time is rotating in the direction of the arrows shownin Figs. 6, 'I and 8, and as the bent end of the wrapper D passesdownwardly through the opening 29 and contacts with the filler in thesocket |6 both the wrapper D and the finger 26 are drawn into the socket|l as shown more clearly in Fig, 8 with the bent portion of the wrapperfolded about the finger 26. The finger 26 makes a complete revolutionwithin the socket IU and is bent to the configuration of the socket H)by pressure of the socket l0 against the end Sp of the filler W. Afterone revolution of the filler and finger 26 in the socket lll the finger26 is dis-` placed longitudinally toward the left of Fig. 3 by itsoperating mechanism shown in Fig. 9.

When the wrapper D is completely disposed about the filler W the cam 23will swing the socket I0 to a released position, shown in dotted linesin Fig. 3. The completed cigar may then be removed from the rollers Iand a new filler inserted and the operation repeated. By means of theadjustable mounting for the socket Il), the axis of this socket may befinely adjusted with respect to the axis of the filler W, and thelongitudinal adjustment of the bar |2 will permit the positioning of thesocket 0 in a manner to firmly press against the adjacent end of thefiller W. The detachability of the socket l0 will permit the use of anydesired socket configuration, and the use of a resilient finger 26 willpermit the use of any desired socket without changing the other parts ofthe device, as the finger 26 will readily adapt itself to any socketconfiguration. The longitudinal adjustment of the socket I0 with respectto the rollers will also permit the use of this structure with anylength of filler, so that a wrapping machine equipped with thisinvention may be used with cigars of different configurations and sizesboth as to diameter and length.

. It will be apparent from the foregoing that the starting end of thewrapper will be rmly and snugly held against the end of the filler,irrespective of the configuration of the adjacent end of the filler, asthe pressure of the socket l0 against the end of the filler W issufficient to effect a bending of the finger 26 coincident with theshape of the socket I0.
